ALASKA EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
122 PM EDT WED APR 16 2014

VALID 12Z SUN APR 20 2014 - 12Z THU APR 24 2014


THE GFS AND GEFS MEANS OF LATE HAVE BEEN SHOWING THEIR PROGRESSIVE
BIAS WITH THE LONGWAVE SPLITTING ALONG THE WEST COAST OF NORTH
AMERICA AT THE MEDIUM RANGE, PRECLUDING THEIR INCORPORATION INTO
THE MANUAL BLEND FOR ALASKA THIS FORECAST. WHILE THE EUROPEAN
CENTRE CAMP LOOKS BETTER OVERALL, NO PARTICULAR OPERATION RUN IS
CORRELATED WELL ENOUGH WITH THE ECENS MEANS TO LEND ITS MORE
RESOLVED MASS FIELDS TO THE BLEND, EITHER. THE ONGOING BLOCKINESS
WILL CONTINUE TO KEEP MOST OF THE PRECIPITATION SOUTH OF THE
ALEUTIANS AND OVER THE PANHANDLE, THOUGH NEITHER OF THOSE REGIONS
LOOK ESPECIALLY WET OR STORMY. TEMPERATURES SHOULD BE SEASONABLE.
